To all flu/om 'it may concern.' Be it known that BENJAMIN M. Bonn- Lnn a citizen of the United States, residing v at debolt, in the county of Sac, State of Jiowa, haveinvented certain new and usefulA Improvements in Manure-Spreaders'j and l do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makel and use the same. f

AThis invention relates to new and useful improvements in fertilizer distributers and generally speaking it includes superposed distributing cylinders, a rake for distributing the fertilizihg material therefrom and a follower for forcing the material against the cylinders.

The object of the invention is to provide a novel construction (.:oinbination and are rftngement of parts, the details of which will appear iii the course of the following description in which reference is had to the accoinpiinying drawings forming a part of this specification, like characters of reference designating similar views wherein7 Figure 1 is a side elevation showing the .fnannei' of use of a fertilizer distributer conparts lthroughout the several structed in accordance with the present in-` vention. F ig. 2 is a central longitudinal section of a manure spreader constructed in accordance with the present invention and showing by dotted lines the various ositions of the follower above referred-to. ig. 3 is a top plan view thereof. Fig. 4 is a detaill fragmentary perspective view -ofsuch follower and its adjuncts. Fig. 5 is a detail view of the rake.

Referring specifically to the accompanying drawings the numeral 1 designates a wagon or conveyer of ordinary form, the sides of which are extended rearwardly as at 2 and support upper and lower transverse shafts 3 and 4, the latter bein disposed rearwardly of the former. The slgiafts 3 and 4, project be Tond one of the extensions 2 and carry belt wheels 5 and the former driving the latter by means of a crossed belt'7. The shaft 3 also carries a sprocket wheelB which is driven by a chain 9 from a sprocket wheel.

10, the latter being carried upon .the power shaft of the conveyer. The extensions 2 are closed by a hood 1-1 which at its lower end carries a transverse rake head 12, the latter being provided with teeth 13 arranged divergently on opposite sides thereof. The sha ts 3 and 4 carry c lindrs 14 and 15, both being constructe with longitudinal bars 16 from which pro`ect teeth 17 employed to comminute the fertilizer. The extensions 2 are provided with straps 18 having laterally projecting pins 19 arranged in series and selected and correspondingpins 19 are engaged through slots 20 rovided in rojecting straps 21, the latter eing carrie by a follower board 22 disposed transversely of the wagon. The provision ofthe pins 19 in series affords means, whereby the pivotal center of the board 22 may be adjusted to selected positions.

When the wagon is being loaded with fertilizer the board 22 is lswung over on the hood 11 and when the wagon has been loaded said board is swung over to lie flat upon the load and press the same a ainst the toothed coinininuting cylinders. t will be understood that the wagon is egluipped adjacent itsr floor with the usual en ess conve Ter 23 operated in any suitable manner. Tie upper cylinder 14 serves to keep the lower cylinder 15 from becoming clogged or choked and the latter throws ythe material outwardly against the rake from which it gravitates and is spread laterallyby: the disposition* of the teeth 13. The hood 11 serves to revent the material from being blown away4 the wind and also serves to protect the mec anism inclosed therein against the elements. The board 22, by virtue of its pivotal mounting affords an efficacious means forholding the load compact as it is fed rearwardl by the conveyor. .The board, in attaining this function, acts by means of its Weight as a gravity follower and moves downwardly on its pivot, upon the load as the latter gradually diminishes in size when it is fed from the wa on.

Irom the foregoing description it will be seen that simple and efficient means are provided for accomplishing the objects of the I invention, but, while the elements herein shown and vdescribed are well adapted to serve the functions set forth it is obvious various minor changes may be made in the proportion shape and arrangement of the several parts,- without departing from the spirit and scope of the invention as defined inthe appended claims.

" What is claimed, is,

1. An apparatus of the type set forth com prising the combination with a Wagon having rearward extensions, of a hood supported transversely between said extensions, a rake head provided at the lower end ofsaid hood,

upper and lower toothed cylinders supported for rotation between said extensions and a follower disposed transversely between the sides of said wagon and piyotally' supported therefrom to lie upon the load in said wagon as and for the purpose set forth.

An apparatus of the type set forth, comprising the combinationl with a wagon having rearward extensions, of a toothed cylinder supported for rotation between said extensions, straps secured `to said extenwith longitudinal slots to surround selected 2o ones of said pins on each of said straps.

ln testimony whereof, l aIiX my slgnature, 1n presence of two witnesses;

BENJAMIN M. BUEHLRR.'
